Pin Description
2
Ground. This pin is connected to ground on the circuit board through a trace. Do not
connect directly to GND plane.
5
Power. This pin is connected to power on the circuit board.

Paddle
These pins should be soldered to pads on the PCB for mechanical stability; they can be
electrically floating or tied to VDD (do not tie to GND).
This pad is connected to GND internally. This pad is the main thermal input to the on-
chip temperature sensor. The paddle should be soldered to a floating pad.
